olene-Tanks, of which the following is a specification.

This invention has reference to improvements in registers and indicators for gasolene tanksof automobiles, and is designed to provide a visible indicator showing at all times the amount of gasolene within the tank and also producing a trip and season registration of'the amounts of gasolene used.

While the prime purpose of the present invention has to do with gasolene tanks of automobiles, the structure is adaptable to other uses where the registration and indication may have nothing to do with gasolene, but with other fluids or conditions, and consequently while for-the purposes of simplicity of description gasolene will be considered as the fluid employed and the gasolene tank of an automobile as the receptacle for the fluid, it is to be understood that the invention is by no means confined to such particular use and the terms gasolene and gasolene tank of an automobile whether employed in the description or claims is to be interpreted broadly enough to include any other devices or materials to which this invention may be applicable.

Ordinarily automobiles are provided with gasolene tanks of considerable capacity, sometimes as high as twenty-five or thirty gallons, and sometimes as low as ten gallons or less, but they are not customarily equipped with any means for showing the amount of gasolene in the tank, or any means whereby the user of the automobile can ascertain except with diificulty, the amount of gasolene which may have been used during a certain period of time or on a trip, while there is no practical means at all provided for registering the amount of gasolene which may be used during a long period of time, such as a season.

The present invention contemplates means which may be so arrangedas to be at all times within ready observation of the oper- .ator of the automobile, whereby the capacity of the tank is indicated, the amount of gasolene which may at any time be within the tank is indicated, the amount of gasolene used within any short period, such as during a trip is registered, and the amount of gasolene which may be used within any long period of time, such'as .a season,.is registered, and all these operations are entirely automatic, except that it is necessary to reset the trip register at the beginning of each trip.

In accordance with the present invention a small instrument which may correspond in size and appearance to the familiar speedometer employed upon automobiles, may be attached to the dash board in such position as to be as readily visible as is the speedometer. The face of the device displays a dial having numbers Which may indicate quantities of gasolene, usually by one gallon steps, up to a quantity representing the capacity of the largest vehicle to which the device may be attached. The face of the instrument also displays numbers, as the gasolene is used, representing the amount per trip and the amount per season. Moreover, the device displays two hands, oneof which is movable by the other, and the second hand is responsive to the depth of gasolene within the tank. The first hand is designed as a permanent indicating hand, and the second hand will, when the tank is initially filled to its capacity, move the first hand to a point on the dial showing that capacity whatever it may be, and this hand remains in the fixed position indefinitely. The second hand, being responsive .to changing levels of gasolene within the tank, plays over the dial in accordance with whether the tank is being filled or the gasolene is being used. If, after the initial filling of the tank the gasolene is used, the responsive hand moves backward over the dial toward the zero position, thus indicating at -.ll times the available amount of gasolene within the tank. When the tank is replenished this hand moves away from the zero position toward the full position indicated by the fixed hand. The indicator provides a ready means whereby the owner of the vehicle may ascertain at any time by observation how much gasolene is put into the tank and if then purchasing the gasolene need pay for only so'much as the indicator may denote. On observing the amount of gasolene in the tank, as indicated at the beginning of a trip on the dial and then the amount indicated at the end of the trip, provided it be a relatively short trip, the difl'erence will indicate the amount of gasolene used withish the tank several times.

out having recourse to the trip register which may be employed for longer trips during which it may be necessary to'replen- The season register is. designed to-indicate larger amounts, so that the running expenses for, say, a year, so far as fuel is concerned, may be readily ascertained by noting the amount of gasolene used during such period of time.

The particular instrumentalities which may be employed will be better understood invention and showing more or less diagrammatically the connections and structures whereby the instrument is operated.

Fig. 9 is a plan view with some parts in section similar to Fig. 8 and showing some higher parts'illustrated in Fig. 5.

Figs. 10 and 11 are views of operating pawls for the hand indicating the amount of gasolene in the tank.

Referring first to Fig. 1 0f the drawings, there is shown a register and indicator 1 having two hands 2 and 3, respectively, and an index 4 over which both hands may sweep, the index being designed to represent units of measurement of the contents of a.

. tank or reservoir, and as the invention is designed more particularly for indicating the contents of the gasolene tank of an automobile, the index may represent'gallons of gasolene. Since for manufacturing reasons itis advisable to have a single index suited for automobiles of different sizes, the extent of the index may be initially such as to show while the particular tank of the automobile upon which the device is assumed to be installed has a capacity of twenty-three gallons, as indicated by the hand 3, which, when the device is installed, is supposed to rest at the zero indication with the hand 2, and as the gasolene tank is filled to its capacity the hand 2 travels overthe face of the index plate of the indicator until the indi cation 23 is reached, the hand 3 participating in this movement, but being so mounted that it will remain in the position to which it has been moved under all conditions of use, wherefore the hand- 3 may be considered as a fixed hand, while the hand 2 is a movable hand showing variations in the contents of the gasolene tank from zero to the full capacity.

To cause movements of the hand 2 the tank may be provided with any appropriate float mechanism controlling a flexible member or. chain 6 having pins 7 thereon properly spaced to indicate units of capacity of the tank, say, gallons, and these pins have in their path a pivoted arm or lever 8 movable into engagement with either one of two oppositely movable spring contact fingers 9, 10, respectively, arranged to engage electric contacts 11, 12, respectively forming the terminals of conductors 13, 14, respectively,

while the fingers 9 and 10 have a common connection 15 with a battery 16 or other source of electric current, and the battery 16 is connected to a conductor 17 on the side to travel in a manner to bring successive pins 7 into engagement with the lever 8, whereupon a succession of impulses is caused through the indicator and register in a manner to produce a step by step movement of the hand 2 until the full capacity of the tank has been reached or a certain lesser amount of gasolene has been introduced into the tank. By appropriate mechanism to be described, the movementof the hand 2, which clockwise, is ragistered, and this registration icator numerals 18 which are changed only when gasolene is introduced into the tank. As gasolene is used, the float will drop andthe pins 7 will rock the lever 8 in a direction to cause a retrograde movement of the hand'2, this movement being ordinarily counterclockwise, so as to travel reversely along the indications of the indicator plate from a highnumber toward zero, and this movement is indicated by the display of numbers 19, the numbers 18 and 19' being'visible through sight openings 20 in a front-plate 21 of the indicator and register 1, which front plate contains theindex numheld "in a casin bers 4 and maybe covered 'by-a glass plate 22 as iscustomary, said glass plate being usual practice acter.

The'electric controller and float responm structures of this charsivemeans for actuating the same do not in themselves form any part of the present invention', being shown more in detail and also described and claimed-in application No. 768,832, for'indicator operating devices for gasolene tanks, filed by me on May the a I 20th, 1913-, v r

Coming now to the construction of the indicator and register 1, the casing 23 is shown as a cylinder providedwith a head a :24 at theend remote from the glass plate together.

22, and this head may be threadedand the correspondingend of. the casing 23 also threaded,- so thatthe parts may bescrewed At the outer rear faceof the head 24 there is formed a lug or boss 25 designed to receive a bolt 26 by means of Y which the structure may be made fast to a bracket,such as indicated in dotted lines at '27 -on made fast. within ready observation distance of the .3, and which in turn may be to the dash of the automobile operator of the vehicle.

' ;Within the casing and inade fast to the v I head 24 by straps 28 or otherwise, 'are two electromagnets' 29,30, respectively, oneside "ductor l7'andthe other sides of these magof each of which is connected to the conmagnets be used, it is preferred to utilize solenoids, and eachsolenoid'has its core terminating in. a rack bar 31, 32, respectively. The rack bar 31 is in mesh with apinion 33 provided with an elongated hub '34and mounted on a shaft 35 having bearings at One end in a block 36 f tt g i finner wall of the head 24. Fast to the ex.

tended hub 34off'the pinion 33- is arch bracket 37 participating in movements of y r V v E l 23 which may follow the other end .fastinla ithe" pinion 33 under the action of the 3 under the circumstances mentioned may be"31. Thi's a rch bracketextends through an opening38 in a plate 39 disposedlaterally of thecas ing and iofabout the same diameter and serving as a support for certain mechanisms. The end of the bracket 37 re- .mote from the hub of the pinion .33 receives a hub portion 40 of a disk 41 mounted on the shaft 35, the shaft having a bearing "in the plate 39 adjacent to the hub 40. The bracket 37 may be made fast to the hub of the disk '41 by aset screw '42, or in any a other appropriate manner.

The plate 39 is arranged at some little" distance back of the face or index plate '21, and between these two plates are other 4 plates 43 and 44, respectively, in spaced rerespectively, towhich reference will hereinafter he made.

The front end of the shaft 35 may be waxially recessed to form a bearing for one end of a stub shaft 48, the other end of which extends through and has a bearing in the plate 43, "and between said plate and the faceplate2l the shaft 48 carries a disk 49 'upon which one set of the numerals 19 may be placed and the numerals on theiparticular disk 49 may represent the unitsof the indicator train of numerals. shown through the sight openings 20 designed. to

display those numerals of the parts moved when the hand.2 is actuated in .thereverse or backward direction, and which numbers indicate the number of gallons of gasolene used during 'a' certain period which may be a relatively .shortperiod, and is consequently designated by the word trip in 'Fig. 1 of the drawings, the numerals 18 being designed to indicate a total; amount of gasolene used during a long period of time,

and hence designated in Fig. 1, by the word. I

season. The stub shaft 48 has mounted-thereon .a

ratchet wheel 50 having spaced teeth 51 about its, periphery, this wheel being provided with an axially extended hub 52 through which and the corresponding portion of the shaft 48 thereflmay be passed a '-key 53, as representative of any suitable .means of permanently fastening the ratchet,

wheel 50 to the stubsh'aft 48. Thedisk 41" "carries a' pawl 54 in position to engage the teeth 51 and urged toward the ratchet wheel 50' by a springl55. fThera-tchet wheel 50 is prevented fromoverrunning by a vdetent'.

spring 56 h'aving one end. 57 shaped .to-e

gage between adjacent ratchet teeth and'the the plate 39..

pest-.58 in turnfast upon Secured to the ratchet wheel 50 is a toothed disk 59 best shown in Fig. 4 and provided with a single tooth 60. Normally in the path of the tooth 60 is a star wheel 61 mounted on a shaft 62 having bearings in the plates 43 and 39 ,and extending through both, the star wheel 61 having an extended hub 63 with an intermediate circular groove or channel 64; and is mounted upon the'shaft 62 to slide. longitudinally thereon, .but is constrained to rotate with the shaft by means of an elongated spline 65. The shaft 62 is prevented from overrunning by a'notched disk 62 and detent spring 63' adapted thereto. The star wheel 61 carries a disk 66 having a single peripheral tooth 67 designed to engage the teeth of a star wheel 68 mounted on a shaft 69, which like the shaft 62 is journaled in the plates 39 and 43, and is secured to the shaft to rotate therewith.- The star wheel 68 is held against overrunning by a detent spring 70 having a free end 71 shaped to lodge between the teeth of the star wheel, while the other end is mounted in a post 72 which may be made fast to the plate 43. The toothed disk 59, star wheel 61, toothed disk 66 and star wheel 68 constitute an indicator train, while the shafts 62 and 69 carry number disks 7 3 and 74, respectively, with numbers visible" through the sight openings 20 of the trip indicator, the numbers on the disk 73 representing tens and those on the disk 74 representing hundreds.

Mounted on the plate 39 and pro ecting toward the plate 43 is a bracket 75 in which is pivoted a bell crank lever 76 having one arm terminating in a fork 77 straddling the hub 63 inthe groove 64, the arrangement bein such that on the rocking of'the lever 76 t e intermediate starwheel 61 may be I moved lengthwise of the shaft 62 into and out of operative relation to thetoothed disk 59 and star wheel 68. J

The shafts 48, 62 and 69 all extend through the 'late 39 and on the side thereof toward the ead.24 ca respective bevel pinions 7 8, 7-9 and 80 eao made fast to its shaft and each pinion has fast. thereto a radially projecting pin 81. The plate 39 adjacent to the casing 33 has fast thereto a block 82 in which is lodged a collar 83 on oneend of a shaft 84 a reduced extension 85. The'shorter portlon'of the shaft 84 extends through an arm 86 projecting. from a slide late 87, and between this arm and the co ar 83 there is introduced a washer 88, while bearingn n the arm 86 'on the side thereof remote m the washer 88 is one end of a spring 89 which may be a leaf spring, the otherend of which is sup ported in a post 90 fast to the plate 39. The shorter portion of theshaft 84 carries a bevel pinion 91 which-may be moved into and out of mesh with the bevel pinion 80,

. of the tank. As the indicator just referred to is the trip indicator it is desirable to rethe shaft being capable of longitudinal movement in its bearlngu The pinion 91 is held to the shaft 84 by a spring washer 92 interposed between one end of the pinion 91 and the spring 89. The other end of the pinion 91 bears against a sleeve 93 on the reduced ort-ion 85 of the shaft and the other end of t is sleeve bears against the spring washer 94 in turn in engagement with one end of a bevel pinion 95 movable into and out of mesh with the bevel pinion 79, and this pinion 95 is'mounted on a sleeve 96 carried by the reduced portion 85of the shaft 84. The sleeve 96has a bearing in a bracket 97 carried by'the plate 39 and serves to support the reduced portion 85 of the shaft 84. The sleeve 96 'at the end remote from the washer 94 bears against a spring washer 98 the corresponding end of the reduced portion 85 of the shaft 84 serves to maintain the pinion 99 on the shaft. The slide plate 87 is held to the plate 39 by headed studs 101 extending throu h elongated slots 102 near the ends of t e late, while the angle or,.bell crank lever 6 has an end portion 103 entered into a slot 104 in the plate to be. moved thereby. The plate 87 has the edge carrying the arm 86 formed with lugs or projections 105 movable into and out of the path'of the pins 81.

The collar 83 has secured thereto a stem 106 either by having the stem threaded and screwed into the collar or in any other apropriate manner, and this stem is of a ength to extend to the exterior of the casing 23'through a passage 107 provided in the'casing and exterior to the casing has a milled head 108 or any other appropriate means for permitting the rotation of the stem 106 and with it the shaft 84 by the hand of an operator. The tendency of the indicator disks 49, 73 and 74 may be moved under the action of the shaft 35, the normal position of the an le lever 76 being such as to hold the star w eel 61 in the path of the teeth 60 and the tooth 67 in position to en-' gage the teeth of the star wheel 68. Under these circumstances indication is made of the number of gallons of gaso ene used out set it m the zero position at the end of each trip or other relatively short period of time. To do this the operator the milled head .108 and by pushing the shaft 1 84 against the action of the spring 89 the gear wheels 91, 95 and 99 are brou ht into mesh with the gear wheels 80, 79 an 78, re-

spectively. At the same time the lever 76 is rocked so as to carry the star wheel 61 and its toothed disk 66 out of the path of the other members of the train and the plate 87 is moved so that the lugs 105 are in.the paths of the pins 81. Now on rotating the 19 milled'head 108 while it is still pressed inwardly, rotative movement is imparted to the shafts 48, 62 and 69 all in the same direction and th' rotative movement con: tinues until the pins 81 come in contact with the lugs 105, at which position the zero indications on the number disks 49, 73 and 74 are coincident with the sight openings on the trip indicator. Whether or not the I pins 81 all engage the lugs 105 at the same 20 time is immatenahfor assoon as a pin 81 engages a lug 105 rotative movement of the I pinion carried by the shaft 84 ceases, since such pinion will then remain at rest, while the shaft continues to rotate because it is connected to the shaft only through the spring washer 92, 94 or 98, respectively. After the indicating numbers have been all brought to the zero position the head 108 ma be released, whereupon the spring 89 move the shaft 84 lengthwise in a diaway from. the pinions in the indicator shafts and return the plate 87 to' its first position with the lugs 105 out of the paths of the pins 81 and the star wheel 61 and toothed-disk carried thereby into operative relation to .the rest of the train ready to again indicate use of gasolene.

a The shaft 35 has secured thereto one end 10 of a spiral spring 109, the other. end of" which is made fast to some fixed portion of I the structure, as, for instance, the block 36, and this spring is put undertension by the rotative movement of the shaft 35 when the t5. solenoid becomes active and when the solenoid is deenergized the spring 109 turns the shaft to its first position ready for subse quent-actuation, and thismovement causes a corresponding movement Of the bracket 0 37 and disk 41 returning the pawl54 to lts first positionready to engage the next tooth 51in order on the ratchet wheel '50, the de-.

':'-The shaft 111, like the 'sha 35, is under the controlof a spiral spring 112 v fast at one end spring 112. vtween the plates 39-and 44 and there carries a disk 113 provided with a hub 114 offthe dis number disks controlled by the 1as'tfdeto the shaft and at the other end toifihe block 36, so that at each energization of the magnet'30 resulting in the indrawing of the rack 32 the rotative movement imparted thereby to their first osition by he'reaction of the he shaft 111 terminates be setting the disk a short distance from the plate 39. In alinement with the shaft 111 and mounted in the plates 43 and 44 is a stub shaft 115 carrying adjacent to the disk 113 a-ratchet wheel 116 best shown in Fig. 5 and similar to the ratchet wheel 50 except that in the particular construction shown it is provided with teeth 117 reversely arranged with respect to the arrangement of the teeth 51 on the ratchet wheel 50. The disk 113 carries a "pawl 118 urged toward the ratchet 7 wheel 116 by a spring 119, as to engage a tooth 117. There is also provided a detent spring 120 having a free end 121 shaped to engage between the teeth 117 'to prevent overrunning of the ratchet 'wheel while the other end of the sprin is made fast to a post 122 k which, may e carried by the plate 44.

The shaft 115 between the plates 43 and 44 carries a toothed disk 123 having a sin.-

rgle peripheral tooth 124 in position to engage a star wheel 125 mounted on a pin or arbor 126 and-held against overrunmng by a spring 127 engaging the teeth of the starwheel, and this star'wheel has fast thereto a disk 128 with a single peripheral tooth 129 in position" to engage the teeth of a star wheel 130 mounted on an arbor 131 between the plates43 and 44- and in turn provided with a detent spring 132. The star wheel 130 is provided. with a disk 133 having a peripheral tooth 134 in position to engage a star wheel 135 also mounted between plates 43 and 44 on an arbor 136, and this 4 ast-named star wheelis held against overrunning b a detent spring 137'.

The hand 2 is mounted upon an arbor 140 extending through the face plate 21 and havin arbor 140 bein in the longitudinal axis of of the casing, t e latter being usually cylin- Mounted on the arbor 140 between the plates 39 and 44 is a disk 141 having an axially extended hub I42 and provided with a peripheral series of notches 143, the latter belng relatively shallow and designed to receive the end 144 of a detent spring 145, the other end of the spring being carried by a post 146 fast on the plate 39.

Mounted on the hub 142 on opposite sides of the disk141 are two-ratchet wheels 147 and 148, respectively, each having a number of teeth corresponding to the divisions of the plate or dial 21 and the teeth of one ratchet wheel are oppositely disposed with reference to those of the other ratchet Mounted on the arbor. 140 between the plates 39 and 44 and on opposite sides of the hub 142 are bushings 149 and 150 and each having a reduced'portion 151 extending through the respective plate. These bushings may serve as bearings for the arbor 140 and mounted on the bushings 1'49 and 150 are rock arms 152 and 153, respectively. These rock arms haveportions 154 immediately surroundingthe bushings broadened so as to bear against the respective plates 44 and 39 and are held in frictional engagement with these plates by respective springs 155 each fast at one end to a plate 39 or 44,

' as the case may be, and at the other end bear against that face of the enlargement 154 remote from the respective plate to which the spring is attached, the springs being shown as leaf springs. By this means the rock arms may be maintained in their relative positions and still be quite thin. Each rock arm carries apawl 156'shown as an angle pawl with a nose l57 shaped to engage between the teeth" of the respective ratchet wheel 147 or 148, as the case may be. Each arm 152 and 153 is provided with a lug extension 158 .ca'rrying a pin 159 in the path of'the respective pawl 156 limiting the movement of the latter away from the teeth of the respective ratchet'wheel. The angle end of each pawl 156 remote from its nose 157 is connected by a link 160 to the respective disk 41 or 113, as the case may be, the construction being such that when the disk 41 or 113,

as the case may be, is rocked, the correspond- "ing pawl 156 is first rocked until its nose 157 is moved into position between two teeth of the-corresponding ratchet wheel 147 or 148 and the continued movementof the disk 41 or 113 causes a corresponding movement of v the ratchet wheel. The parts are proportioned so that a movement of the disk 41 a journal bearings in the part 45 of -the p ate 44 and also in the plate 39, the

distance corresponding to the distance between two adjacent teeth 51 will result in a movement of the ratchet Wheel 147 a distance which will rotate the arbor 140 sufliciently to move the hand 2 in the counterclockwise direction corresponding to the space between two unit divisions of the dial 21 A like movement of the disk 113 will engagement with the teeth of the respective ratchet wheel, whereupon a further movement of the disk 41 or 113 causes a rocking of the arm 152 or 153 sufliciently to bring the pawl into position to be moved into active relation to the next following tooth in order of the respective ratchet wheel, so'that when the respective disk 41 or 113 is again actively moved, the nose 157 of the corresponding pawl is first moved into position between two successive teeth and then the corresponding ratchet wheel is actuated in the manner already described.

To prevent tampering of the electrical conductors they may be in armored form known in the trade as BX cable. Such a compound conductor is carried through a passage 161 in the boss 25 on the head 24 and any s stem of wiring may be-employed which wil prevent access to the conductors.

To properly space and hold the plates 21, 39, 43 and 44 any suitable supports therefor may beprovided. For instance, rods or pins 162 are shown in the drawings as made fast at one end to'the inner wall of the head extend to the plate 39. Inalinement with the rods 162 are spacers 163 between-the plate 39 and the plate 44. Between the plate 44 and the plate 43 are other spacers 164 and each spacer 163'and 164 has a stem continuation 165 extending through the respective plates 39 and 44 and threaded into the spacers 163 or rods 162, as the case may be, as-indicated at 166, thus clamping the respective plates between them. The dial plate 21 is secured to the plate 43 in spaced relation thereto by screws 167 and spacing washers 168, while the dial plate may be recessed, as indicated at 169, to accommodate the disk 73 on the trip registering mechanism.

By the construction described the parts may be all readily assembled, after which l t i'o duced 't t nkrthe level or liquid-jth i is I ring 170, as is customary.

Assuming that .the indicator and register is installed upon an. automobile withthe.

At each energization of the magnet 30 the shaft 111 has a partial rotation imp'arted thereto and ,each time the magnet or solenoid 30 is deenergized the shaft 111 is rocked in the other direction to its first position by the spring ;112. Each rocking movement of the shaft 111 fcauses a corresponding rocking movement of the. -.-disk 113 and this movement is transmitted through the link'116 to'the pawl 156 and rock arm 152, thus resulting in a clockwise sponding' movement ofthe hand 2 which in turn carries the hand 3-with it.
